Hello,
Thank you for your post and welcome to the VIH forum in Spanish. I will reply to you first of all in English, and then I will translate the answer into Spanish for the benefit of the Spanish speaking community.
First of all, I have to say that you dod not put yourself at any significant risk of HIV infection and from that point of view, you would not even need testing. Therefore I can assure you that you are negative. On the other hand, one cannot consider the instant antibody test fully conclusive after only thirty days following exposure. One would need to wait a minimum of eight weeks. But in any case, this is irrelevant in your case because you did not put yourself at risk. Your itchy bum has absolutely nothing to do with that sexual encounter, and even less with HIV.
Best wishes,
Dr. José
TRADUCCIÓN AL ESPAÑOL:
Se me pregunta si la prueba rápida de anticuerpos del VIH es válida a las cuatro semanas, ya que obtuvo un resultado negativo treinta días después de haber realizado sexo oral en un hombre durante diez segundos. También se preocupa por el hecho de haber desarrollado una erupción de granos con picor en el trasero.
Mi respuesta intenta tranquilizar a esta persona ya que no ha habido ningún riesgo en el acto sexual en referencia al VIH y por lo cual no requeriría incluso hacer la prueba. Sin embargo en referencia al tipo de prueba, el test rápido de anticuerpos o Insti/Rapid solamente se le puede considerar totalmente fiable a partir de al menos ocho semanas desde el momento de la posible exposición al virus. Pero en el caso de esta persona esto no es relevante ya que no corrió ningún riesgo de infección por VIH.
Los síntomas de granos en el trasero no tienen nada que ver, ni con el acto sexual en cuestión, ni con el VIH.
Un saludo a todos,
Dr José
